FOLDING MACHINE.

application filed September 24, 1926. Serial No. 137,451.

rl`his invention relates to {Hiper-folding 1naehines o1 the type in which the paper is lolded by a buckling operation as described in the Johnson Patent No. 893,629, dated July 21, 1903.

it one ot the objects of the invention to provide an improved Yforni of mounting for the iold plate which will permit the saine to be readily. conveniently and accurately aligned with the :folding rolls and avoid the usual fitting and trying, which has been here tor'ore necessary in connection with the manu facture of folding niacl'iines.-

Other objects o1" the invention and the 'ifeatures ot novelty will be apparent `from. the following description taken in connection with the accompanying drawings, of which z Il 1 is a longitudinal section through a portion oit the `folding machine embodying iny invention, the section being on the line 1-1 of Fig. 2;

Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 3 is an enlarged section on the line 3 3 oi" Fig. 1; and

Ifig. is a section on the line H of Fig. 1.

Referring to the drawings, and 11 indicate the side nieinbers of the frame of the machine and 12, 13 and 1st, `the usual feeding and folding rolls. ihe told plate is indicated at 15 and is slidably mounted on the angle bars 16 and 17, whicliare secured on the ineinhers 10 and 11, respectively. As is well understood by those vl'aniiliur with folding inachines, it is necessary that the lower odge 18, or' the ifold plate, be accurately aligned and positioned relative to the rolls 12, 13 and 14eA and, according to prior constructions. this has required considerable trying and fitting ot the told plate. which has involved a considerable amount of time and expense in building the machine. In order to overcome this disadvantage of prior construction, I have provided means for adjusting the bars 16 and 17, on which the iold plate slides, so as to properly locate the lower end 18, of the old plate. Each oit the bars 16 and 17 has, as one of its securing ineens, a bolt 19 on which the baris adapted to pivot. In this nianner, the angle of the fold plate .may be adjusted and the angle of either side of the fold plate may be adjusted indcpciulently of the other side by inovcinent ot one ot the bars 16 and 1T on its bolt 10. In order to accomplish this independent adjustment of the bars 16 and 17. I have provided the eccentric pins 20,'which are mounted in the frame members 10 and 11, as shown in Fig. 4. The pins 20 extend through slots 21 in the bars 16 and 17 so that by rotating these pins, the lower ends of the bars may be raised or lowered, to properly align the lower end 18, of the fold plate, with the rolls 12, 13 and 14. When this relation has been properly established, the bolts 1S) are tightened and the pins 2O are secured in their adjusted postion by any suitable device, such as a set screw or the device which will be presently described.

The fold plate is slidable on the bars 16 and 17 and, in order to confine it to its adjusted position', I provide stops 2:2 which engage the transversely extendingr abutments 23, in the side edges of the fold plate. The fold plate is held down on the bars 16 and 17 by means of adjustable eccentric pins 24; and these pins may be similar to the pins 2O and, the method of securing them is equally applicable to the pins 2G.

The Shanks 25, or" the pins 24, are longitudinally split and there is a longitudinal opening through each pin 24., to receive the tapered pin Q6. iV hen the pin 26 is driven into its opening. it expands the shank so that the latter 'will be tightly secured in its opening in the frame. A set screw 27 is provided for the purpose of holding the tapered pin 26 in the position to which it is driven. lVhen it is desired to adjust the pin 24, the set screw 97 is removed and the pin 26 is driven to the left, in Fig. 3, thereby permit-ting the sections of the shank 25 to contract, so as to free the pin from its opening in the frame. A screw driver may then be inserted in the slot 28 and the pin 24 turned to its desired position, after which the tapered pin 26 is again driven tightly into its opening and the set screw 27 replaced.

Having thus described iny invent-ion, what l claim is:

1. In folding machines, the combination of a frame, a pair of supports on said frame, a fold plate on said supports, feeding and folding rolls with which said fold plate cooperates, and means for adjusting said supports to align said fold plate with said rolls.

2. In folding machines.v the combination f a traine. a pair oi' supports on said traine` a fold plate on said supports, feeding and folding rolls with which said fold plate cov operates, and means` for independently adjusting said supports to align said fold plate with said rolls.

3. In folding machines, the combination of a frame, a pair of supports on said frame, a fold plate on said supports, feeding and folding rolls With which said fold platev cooperates, pivots on which said supports are mounted and permitting angular adjustment thereof, and members for adjusting said supports to align said fold plate with said rolls. 4. In folding machines, the combination of a frame, a pair of supports on said frame, a fold plato on said supports, feeding and folding rolls With which said fold plate cooperates, pivots on which said supports are mounted and permitting angular adjustment thereof, and rotatable eccentric members for adjusting said supports to align said fold plate with said rolls.

5. In folding machines, the combination of a frame, a pair of lsupports on said frame, a fold plate on said supports7 feeding and folding rolls With which said fold plate cooperates, bolts for securing said supports to saidframe and on which the supports are an- Qularly adjustable, rotatable eccentric members carried by said fra-me and engaging slots in said supports for t-he purpose of angularly adjusting said supports, and means whereby said eccentric members are secured in any position to which they are adjusted.

In testimony whereof, I hereunto aix my signature.
